Answer Posted / man

the load of generator is always a mechanical load which do
not bring about any appreciable change in the power
factor.hence its rating is in KVA.where as in motor the load
is electrical load and it brings about change in power factor
so its rating is in KW.

why do motors burn out? I understand why adding parallel loads to a power source means more current moves through the circuit, and can destroy circuit elements by overheating. What about when you have a vaccuum cleaner intake flush against a floor, a room fan sitting directly against a wall, or a power drill trying to drill through something too hard?
